Explanation:
Detailed explanation-1: -Example: a car going down different surfaces. Independent variable: the surface of the slope rug, bubble wrap and wood. Dependent variable: the time it takes for the car to go down the slope. Controlled variable: the height of the slope, the car, the unit of time e.g. minutes and the length of the slope.
Detailed explanation-2: -Velocity, energy, mass, position, angles, temperature, charge. Some variables like acceleration can be reduced to more fundamental variables. These are all variables in physics which shape our understanding of the world. These variables are bound together through equations.
